BEA: Revisiting anchor-based object detection DNN using Budding Ensemble Architecture

no code implementations14 Sep 2023 Syed Sha Qutub, Neslihan Kose, Rafael Rosales, Michael Paulitsch, Korbinian Hagn, Florian Geissler, Yang Peng, Gereon Hinz, Alois Knoll

The proposed loss functions in BEA improve the confidence score calibration and lower the uncertainty error, which results in a better distinction of true and false positives and, eventually, higher accuracy of the object detection models.

Exploring Resiliency to Natural Image Corruptions in Deep Learning using Design Diversity

no code implementations15 Mar 2023 Rafael Rosales, Pablo Munoz, Michael Paulitsch

We compare ensembles created with diverse model architectures trained either independently or through a Neural Architecture Search technique and evaluate the correlation of prediction-based and attribution-based diversity to the final ensemble accuracy.

Evaluation of Confidence-based Ensembling in Deep Learning Image Classification

no code implementations3 Mar 2023 Rafael Rosales, Peter Popov, Michael Paulitsch

The key idea is to create successive model experts for samples that were difficult (not necessarily incorrectly classified) by the preceding model.
